Automated Keyword Research Tool

Hi,

First thing first: I know how to do keyword research and currently I'm using Market Samurai. But the thing is that, most of my clients (quite a number) would want to try doing this kind of work. They want to be more of involve and I don't have any problem with that considering that (1)now they know how difficult doing kw research (2)minimizing my workload esp. explaining why I choose those set of keywords.

One thing though is that a lot of them don't really know SEO and as we all know, they have a greater tendency to just randomly pick kws, making me: "What the are you doing?"

With that, I'm soliciting some advise about a keyword research tool that is simple and most importantly automated(would pull/suggest keywords for you: e.g massage - it would pull all the related massage keywords).

Thanks ahead!

By the sound of things your clients want something simple to use? Is this correct?
